When I first start my diffuser during thicker ice cover (3"-6") I go out and ice auger a hole above the diffuser. This right away allows air to escape and bubbling at surface quickly melts into a larger ice free area. Once I get an open area that refreezes at night, the next day's aeration period fairly quickly melts the ice that froze overnight.
